The Ruling on Swearing by Trust
Machine translationRead the Arabic original
Question:
May Allah reward you. The questioner asks: Is it permissible for a person, if he wants to confirm that he is speaking the truth, to say "by trust"?
Answer:
It is not permissible to swear by trust; this is shirk (associating partners with Allah). Swearing by trust is shirk, just like swearing by other than Allah (Mighty and Majestic). It is not permissible. Even if the prohibition came, the prohibition came regarding swearing by trust. Whoever is swearing, let him swear by Allah or let him remain silent. Yes.
